Answer 1

The correct option is A Both assertion and reason are true and the reason explains the assertion

When certain exotic species are introduced into a new geographical area that is not native to them, they spread really fast since they do not have their natural predators in the new area.

One of such examples is introduction of water hyacinth in India. Water hyacinth invaded the water bodies very fast in India due to lack of natural predators.
